    2019

  • Engineering and Construction Bulletin 2019-03: Risk Informed Decision Making for Engineering Work during Planning Studies
    This Engineering and Construction Bulletin (ECB) outlines concepts, goals and provides interim guidance for the engineering and construction components associated with planning studies under the DirectorÂ’s Policy Memorandum CW 2018-05 issued in May 2018, Improving Efficiency and Effectiveness in USACE Civil Works Project Delivery (Planning Phase and Planning Activities). A maxim of execution is that expedience is not to be prioritized over sound engineering judgment. The concepts in this ECB can also be applied, as appropriate, to other risk-informed efforts.
  • Engineering and Construction Bulletin 2019-15: : Interim Approach For Risk-Informed Designs For Dam And Levee Projects
    This Engineering and Construction Bulleting (ECB) provides interim guidance for incorporation of risk-informed design into on-going and future projects across all phases of work, including those in the FY18 Disaster Relief Supplemental Appropriations, for dam and levee projects. Project outputs during the study phase help guide design of projects, and as this ECB points out, risk-informed design changes need to be evaluated to determine if the changes stay within the Chief of Engineers' discretionary authority or require re-evaluation. Planners often support engineering and design teams in making this determination. Note: This ECB compliments Planning Bulleting 2019-04: Incorporating Life Safety into Flood and Coastal Storm Risk Management Studies.
  • Engineering and Construction Bulletin 2019-8: Managed Overtopping Of Levee Systems
    This Engineering and Construction Bulletin (ECB) provides an interim update to expired ECB 2017-15, Managed Overtopping Of Levee Systems and technical guidance Engineer Technical Letter (ETL) 1110-2-299, Overtopping of Flood Control Levees and Floodwalls, and provides a methodology for configuring the engineered capacity exceedance related to flood overtopping at a specific location or locations along the levee system. This guidance does not address overtopping of the entire system on those occasions when the overall system capacity is exceeded. Content of this ECB supersedes previous guidance on the subject of overtopping of levee systems and will be incorporated into an Engineer Manual (EM) in the future.
  • Engineering and Construction Bulleting 2019-11: Transition Guidance For Levee System Evaluations For The National Flood Insurance Program (NFIP)
    This Engineering and Construction Bulletin (ECB) directs that USACE cease using EC 1110-2-6067, USACE Process for the National Food Insurance Program (NFIP) Levee System Evaluation for all new levee evaluations for NFIP mapping purposes initiated after the date of issuance, and begin using the process set forth in Appendix B of this ECB or successor guidance. As USACE and FEMA move to risk-informed levee evaluation processes, this ECB provides guidance explaining how to transition USACE Levee System Evaluation Reports (LSERs) from the process set forth in EC 1110-2-6067 to USACE accreditation recommendations using risk assessments as outlined in Appendix B.
  • Engineering and Construction Bulleting 2019-13: Methods For Storage/Yield Analysis
    This Engineering Construction Bulletin (ECB) provides technical guidance on theories, methods and application of reservoir water supply storage/yield analysis.

    2018

  • Engineering and Construction Bulletin 2018-14: Guidance for Incorporating Climate Change Impacts to Inland Hydrology in Civil Works Studies, Designs, and Projects
    This Engineering and Construction Bulletin (ECB) reissues and updates the policy in ECB 2016-25, Guidance for Incorporating Climate Change Impacts to Inland Hydrology in Civil Works Studies, Designs, and Projects. This ECB applies to all hydrologic analyses supporting planning and engineering decisions having an extended decision time frame (i.e., not for short-term water management decisions). It provides guidance for incorporating climate change information in hydrologic analyses in accordance with the USACE overarching climate preparedness and resilience policy and ER 1105-2-101.
  • Engineering and Construction Bulletin 2018-15: Technical Lead for E&C Deliverables
    This directive continues the requirements set forth in EC 1165-2-217, Review Policy for Civil Works, 28 February 2018, which are currently being written into permanent USACE policy. This policy applies to all E&C deliverables executed by, or through, USACE labs, centers and districts for all stakeholders.
  • Engineering and Construction Bulletin 2018-2: Implementation of Resilience Principles in the Engineering & Construction Community of Practice
    This ECB provides the policy and guidance for applying the USACE principles of resilience - Prepare, Absorb, Recover and Adapt (PARA) - to Engineering & Construction (E&C) Community of Practice (CoP) efforts.
  • Engineering and Construction Bulletin 2018-3: Using Non-NOAA Tide Gauge Record for Computing Relative Sea Level Change
    This ECB outlines concepts and goals, provides guidance, and introduces a tool for estimating relative sea level change (RSLC) using long-term tide gauge records other than National Oceanic and Atmospheric Administration (NOAA) National Water Level Observation Network (NWLON) tide gauges. Examples of long-term non-NOAA tide gauges are those operated by the U.S. Army Corps of Engineers (USACE) or the US Geological Survey (USGS) within the coastal zone.

    2017

  • Engineer Technical Letter 1110-2-3: Guidance for Detection of Nonstationarities in Annual Maximum Discharges
    This technical letter provides USACE with guidance for detection of abrupt and slowly varying changes (nonstationarities) in analyses of annual maximum discharge supporting USACE project planning, design, construction, operations and maintenance.
  • Engineering and Construction Bulletin 2017-15: Managed Overtopping of Levee Systems
    The U.S. Army Corps of Engineers (USACE) will use this directive and guidance for commands responsible for planning, design, construction, and operation and maintenance of civil works projects. The procedures are general in nature and can be applied to any phase of study, as directed by Engineer Regulation (ER) 1110-2-1150. The level of detail in the overtopping analysis will depend on the study phase. This document is applicable for all USACE riverine levee and floodwall systems. This Engineering and Construction Bulletin (ECB) provides an interim update to expired technical guidance Engineer Technical Letter (ETL) 1110-2-299 and provides a methodology for configuring the engineered capacity exceedance related to flood overtopping at a specific location or locations along the levee system. This guidance does not address overtopping of the entire system on those occasions when the overall system capacity is exceeded. Content of this ECB supersedes previous guidance on the subject of overtopping of levee systems and will be incorporated into an Engineer Manual (EM) in the future.
